LIQUID-COOLER.

SPECIFICATION formingpart of Letters Patent No. 642,456, dated January30, 1900.

Application filed June 29 l 8 9 9.

To all whom it may concern.-

Be it known that I, LARS C. IBSEN, a citizen of the United States,residing at Irene, in the county of Turner and State of South Dakota,have invented a certain new and usefulMilk or other Liquid Cooler, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to milk or other liquid coolers.

The object of the invention is to provide a cooler through which theremay be a constant circulation of cool water from a spring or well pastand on opposite sides of a plurality of annular milk-containingchambers.

The invention consists in certain constructions and combinationshereinafter described and claimed.

In the drawings, Figure 1 is a plan of my improved cooler. Fig. 2 is asection of the same on the line 2 2 of Fig. 1. Fig. 3 is a section ofthe same on the line 3 3 of Fig. 1 and shown as being immersed in abarrel or like inclosing vessel. Fig. 4 is a perspective of the outershell or part of my cooler. Fig. 5 is also a perspective of an innerpart adapted to be inserted within the outer shell, and Fig. 6 is aperspective of water-supply tube.

1 is a barrel or receptacle of suitable character within which myimproved cooler is to be arranged when in use.

2 is ametallic vessel having a copper or noncorrodible outer surface anda tinned inner surface. This vessel is provided with an internal hollowcylinder or drum 3, having a pipe 4Eleading into the top or upper endthereof from a source of water-supply. The vessel is also provided atits upper end with an annular enlargement 6, from which leads a cream ormilk spout 7. There is also provided within the enlargement a pocket orgland 8, through the bottom of which is a passage 9 for the overflow ofwater from an interior vessel to the barrel or inclosing vessel.

10 is an interior vessel carrying an interior concentric open-endedcylinder 11. Attached to the side of the concentric cylinder 11 is awater-supply pipe or conduit 12, leading from the main water-supply. Thevessel 10 is provided with an overflow-spout 13 for the overflow ofwater into the pocket 8 in the outer vessel 2. The vessel 10 is of adiameberial No. 722,313. (No model.)

ter such as to pass freely into the main vessel 2 and leave an annularmilk-space 1% between its exterior and the interior of said outervessehand in order to center the vessel 10 within the vessel 2 I providea series of inclined lugs 15. Leading from one'side of the upper end ofthe cylinder 11 is an over-- flow-spout 16 for the overflow of foam tothe annular enlargement 6, so that it may escape through'milk or creamspout 7. The interior vessel is also provided at the bottom with aseries of supports or feet 17 17 to hold the same away from the bottomof the outer vessel, so as to provide a continuous milk space or chamber14 between the walls 3 and 11 and the walls 2 and 10.

For conveniently and simultaneously supplying water and conducting it topipe or passage 4 and conduit 12 I have provided a branched supply-pipe18. (Shown with particularity in Figs. 2and 6.) The outside of theinterior vessel and the inside of the concentric open-ended cylinder areprovided with tinned surfaces, and the opposite sides of said parts areprovided with copper or non-corrodible surfaces, so that the surfaces incontact with water will be non-corrodible and the surfaces with whichthe milk is in contact will not be corroded or affected by the milk incontact therewith.

In operation cool water from a spring or well is conducted throughbranched supplypipe 18 and through pipes 4 and 12 to the apparatus. Thewater passing through pipe 4. fills the cylinder or drum 3, passesbeneath the same into the barrel, and thereby surrounds the vessel 2.Water through pipe 12 fills the space between vessel 10 and openendedcylinder 11 and overflows through spout 18 into pocket or gland 8 andthence into the barrel. The overflow from the barrel may be conductedaway in any suitable manner. Circulation of water having beenestablished through the cooler, milk or cream is introduced to the mouthof 11, passes by gravity into the annular compartment 14, and thence outthrough spout 7.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. A milk-cooler involving the combination of an outer metallic vesselhaving an internal hollow cylinder or dru m, an annular enlargement atthe upper end, a milk-overflow spout 7 leading from said enlargement, apocket also formed in said enlargement, having a passage leading fromits bottom, and an inner vessel having an interior concentric openendedcylinder, a Water-overflow spout leading from the vessel, and afoam-overflow spout leading from the concentric hollow cylinder, andmeans for introducing water, substantially as described.

2. A milk-cooler involving the combination of an outer metallic vesselhaving an internal hollow cylinder or drum, with water-supply pipecommunicating with the drum and having an annular enlargement with amilk-overflow spout leading therefrom, and a pocket in the enlargementwith a passage leading from the bottom thereof, and an inner vesselhaving an interior concentric cylinder with Water-supply pipe leading tothe bottom between the vessel and its concentric hollow cylinder, awater-overflow spout, and a foamoverflow spout, substantially asdescribed.

3. The combination of a barrel or inclosing vessel, and a metallicvessel having an internal hollow cylinder or drum with watersupply pipecommunicating with the drum and having an annular enlargement with amilk-overflow spout leading therefrom, and a pocket in the enlargementwith a passage leading from the bottom thereof, and an inner vesselhaving an interior concentric cylinder with water-supply pipe leading tothe chamber between the vessel and its concentric hollow cylinder, awater-overflow spout, and a foam-overflow spout, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
